Gamebird. We feed ours turkey feed. I don't know what the protein level is but it is a lot higher than 20%. Our straight run meaties dress out in the 11 to 13 pound range at 10 to 12 weeks. It is a good idea to put something like Broiler Booster available from Murray McMurray in the water. It helps prevent leg and other problems. Also limit the feed to 12 hours on and 12 off starting at about a week of age.
